/dev/mtd/4: No such file or directory

Compiling and installing r4294 (before this I used r4051) I came across a 
problem with flashfs:
[root@asus-router root]$ flashfs commit
/dev/mtd/4: No such file or directory
[root@asus-router root]$ ls -la /dev/mtd/

Historically, flashfs grows from down to top of physical flash. It was simply 
overwritten by firmware due to size increase. Just restore flashfs from backup.

Okay, how can I restore flash if i can not take access to device in which flash 
must locate?

I can't reproduce problem, which device you has?

Works for me.

Such situation can be happened only if your customized FW image are too large 
to has free space for flashfs.

Thanks a lot, only question - how to calculate free space for flashfs after, 
say, making new firmware? Or maybe that question preferable for forum, not 
issues list? =)

total flash size = CFE + nvram + FW + flashfs(min 64K)

эта ошибка возникает когда или повторно 
или еще как то применяются патчи на ядро

нужно удалить сорсы ядра - потом заново 
скопировать и один раз применить патчи
